Figuren 4 and v5, details lto be referred to. y, A Y A c; I, .Ourintention relates to that class of lmachines for laying and twistingrope for which Letters Patentof I the United Statesjvere granted to uson the 28th`day of February, 1844, and-oni thev V25th day of April,'1854, 1

In the former patent astraight crane isv described as being `employedfor' guiding the rope as it was wound upon -f 'the 'winding-reelfhutasthe end of 'thecrane traversed' the arc of a circle, therope, when ateither end of the 4r'eel,'1vas drawn at such an angleV that it: couldnot he woiund ivith regularity, while, when -at the centre, the coils,

were'liable to ride upon eachother, .thereby causing delayaniinconvenience. We afterward ernployed a curved f crane, having anangular arin'fhing-edfthereto,"ca descifibedA in' ouraforesa'id'lpatcntof I.1.854, so as no ,cause the rope-tube fdiuadireetion parallel withlthejaxis of the' win'cli'gerce-l.l But although this device answered.-it; ara :nti ifs-'ny' -reompnsiijfmeseafarer@- mns timed fertnsvascomplicata and' t Our 'present invention :has for its 'object toovercome entirely the above-mentioned diicurties, aud consists inthe-employment, in 'ccnnectin'with acrane, of @guide-Wheel or'pulley',which slideson a horizontal rod o r shaft parallel' with-the exis of thewinding-reel, the-rope nassing from the endof `the 'c'raue .overtheslidin/gfl guide fiulley, and thence vto the winding-reehbywhi'ch' meansit is guided-accurately, as required to forni aperfeeteoil .j l r l;

Omi invention also consists' inlan'improved device for insuring theregular and equis-l.deliverylr of the strands.

In our aforesaid patent of ,1844, each strand ives-` passed once aroundafragivheel, these ragwlzeels heilig each `provided ivithacog-nheelwhich engagedwith s central cogwheel so as. to securetheirsmultanebis revolution. 'The s tra'nds,.hw cver,hivere liable toslip upcn. these rag-wheels as soon 'as ythey becaine `worn', thuscausing aul unequal delivery o ftheyarn, Y To overcome this didiculty wepass each. strand several times around jilsm'ooth rcllor cylinder, soeste prevent its slipping thereon, the rolls being providedwith gears,

- which engsgeih'lthj'. centralfgear to insure their simultaneousrevolution, and atieeter o'r ring provided with vnniiicliiie orinjclinesbeing'applied to' each rollte keep the celsinthei proper position, andpreventtheiiig-froni marinera whichlivehave carried ito'nt.A

'.lo enable'cthersskilled in. the art to understand' and useoiirsinvention, ive-will prcceefi'to'describethe i Inthe r saiddrawings, A-is the' baseiof Athe lmachine, from ivhich rises a. post .orstandard, B, an arm,`,G,

{r1-cjietin'g from"the tofl ofi" which supportsthe upper'end of averticalshaft, D, the lower' extremity of `which -rggidve's'inasnitabl'eibe'arin gv,'al This shaft D carries two circularlplates,'v?1l F, in suitable bearings, in which 'ih ifblfve the'journals cfthswinging' frames Gr, whzicl'rcar'ry the bobbins l uponwhich the stranden a're'wound.

,Thcfshort cranks al, vvhi ciiV are attachedto the endsio'f the journalsof the swinging frames G, have theirjournals in ai circular platerorring, H, which `fits overn eccentric, I, the hollow .shaft of which fitsover the shaft.

v VA1),'and carries a pulley, e, over which passes a ba which passesover 'the pulleys g h, and over a pulley, seen dotted-in fig. 2,se/oured'to the shaftD, so t as this shaft D is revolved by gearingconnected with-the driving-shaft J, the pulley with its eccentric, is4clved in'an opposite direction, so 'aste cause the hobbin-f' framesGtoturn 'on their axes, and thus give theirequired twist 'to .the strandsas they are being formed into rope in n rnanner similar to thatdescribed in .our aforesaid Letters Patent of 1854 but as this formsnopart of our presentinvention, it will not be further described. Therope j, after being laid, passes overthe pullejs l l to thejaulley K,around which it is .ivound several-nimes, and this pulley is revolvedat' the requisite speed by a series of gears, L, connected with thedriving-shaft. The rope is then led over the pulleys m n o tothe rosascrane M, whichy consists of a straight, horizontal bar, 6,.and avertical bar 7, whih s, pivoted to a standard` j), so that thehar 6 willswing freely in a horizontal direction. The rope is led from thfepulley'. o over the pul leys q t' s t of the crane M, and over aguide-pulley, N, to the winding 'or take-up reel O, which is revolvedhymeans of a friction-wheel, P, connected with the gearing L; Theguide-pulley Nis provided u'ith 4a hollow shaft, w, iig. 1, which slidesfreely on a horizontal shaft` or rod, Q; secured between thestandards'lft, and parallel with the axis of the reel O; and itwillrheseen that as the rope'V is vvound up on'the reel O, the guide-pulley Nwill he moved horizontally on the shaft Q, the crane swingingwith it atthe same time, thus insuring the rope being always drawn from the pulleyto the reel in aline at, right angles to its axis, Without regard to theportion ofthe reel on which it is being wound, thus preventing allliability of the coils ridingv upon each other, and insuring their beinglaid on the rail with uniformity and. regularity. This device issimple`and not liable' to get out of order, while the cost of applyingit is very trilling. I

We will now prt ceed to describe the manner in which the regular andequal delivery of the strands c is effected.` v, fig. 4, are rolls orshort cylinders, of equal diameteigwhich vrevolve on hollow verticalshafts w, forming prolongations of the journals of the bobbin-frarnes G,and each of theserolls v carries a gear, y, which engages with a centralgear, S, which revolves loosely on the shaft D, by which means the rollso'are prevented from revolving independentlyof each other; and theserolls are held in place on the shafts 'zo by means of bentguide-piecesa, screwed on to their upper ends, as seen in figs. 2 and 4.4The strands lc areled from the bobbinsnp through the hollow shafts w,and down over the grooved 'portions 8 of the bent guide-piecesfa-r tothe rolls v, around which they are wound five or six Vtimes to preventthem from slipping, and arethenee led' up over the grooved portions 9,and through the openings in the cross-bars 10 to the point vhere therope is being laid." And it will thus be seen that as the strands c arewound around Athe rollsrv La suilioient`nu1nb'er- `ot' times toA preventthem from slipping, andas the rolls are of the Vsame diameter, and areall caused to revolve simultaneouslyat an equal speed by 'means ofth"gears above described, the regular and equal delivcny of'the strands isinsured as required to form perfect work, and the rollsv being placedabove the'plate. E, are always in a convenient and accessible position.vb are rings, the under sides of which are inclined `at 11 12, solas 'tofzorm eeters, and these fleeters are applied to the rolls v soas tocause the strands to'lbe wound up regularly thereon, and prevent thecoils' from riding upon eachother as the rolls are revolved. The ieetersb', Awhichjit loosely on the rolls v, are. kept in placeand preventedfrom revolving with them by projections 13,-which'resit against theguidefpieces a', and,` as an incline is lformed 'on each side of theprojectionl, thefstralidsuiay bu wound around the rolls, either to theright or the left, `as may be desired. v

. Claim. Y

What we claim as our invention, and desire to secure by Letters Patent,is- A `',ihe slidng'guide-pulley N,in combination with the crane-M andthe winding-reel'O, operating Isubstan'- tially asdeseribed for thepurpose set` forth.

We also claim the rolls v, so arranged as to revolvesimultaneously, theguide-pieces a', or their equivalents, for the purpose of insuringtheequal deliver tially as described.
